Is there an app or utility to build the Media list without using the router? I have attempted several times already to create a media list to my USb HD but it stalls and hangs when the Database reaches 60kb.

Is there any way to build the media list on the usb HD manually by attaching it to a PC and creating the Database using it? Then reattaching the said USB HD to the Tomato router and let the router read the created media list database?
